problem details
This low mileage car will often not respond to the remote key opening command. Once in, starter will not respond to either the card/button start nor to the key in ignition start. I have had the position sensor replaced at the cost of $1,400, but the problem is even now worse. I have had the left door locking assembly replaced as well and have dumped about $2500 in repairing this problem. Still no success.
